Capitalism vs. Socialism, Coca-Cola vs. Pepsi, Batch Ingestion vs. Real-time - these are all classic examples of conflict in the world, and everyone has an opinion on what is better. As a Data Engineer, I face the dichotomy between batch and real-time data ingestion daily, making the topic of real-time data ingestion tools highly relevant.

In today’s fast-paced digital world, real-time data ingestion tools have become a crucial component for businesses aiming to stay ahead. It’s simply impossible to do everything as batch processes anymore. If companies wish to compete at the top level, they need to implement either real-time or near real-time ingestion to leverage live analytics, providing second-by-second insights into their business.

In this article, we’ll explore what real-time data ingestion is, the tools available on the market today, and how they can help streamline data pipelines. Let’s dive in!

What is Real-time Data Ingestion?

Real-time data ingestion is all about processing data as soon as it's generated without any noticeable delay. Similar to how humans listen and respond in real-time during conversations, real-time data ingestion tools allow systems to capture and process data continuously.

Designed to handle data immediately, real-time ingestion can be crucial for applications where every millisecond matters. This real-time data might come from dynamic systems that constantly change, such as wind turbine sensors, stock market signals, or traffic management systems.

What is Near Real-time Data Ingestion?

Some data systems also implement near real-time data ingestion which is a bit slower than real-time, but still pretty fast! It means we implement a small, but acceptable delay between when the data is generated and when it's processed. It's like when you're texting someone and they respond within seconds – not quite instant, but close enough.

This small delay might not be a big deal for some applications, like monitoring website analytics or social media feeds, and the cost savings from implementing a near real-time ingestion system like this outweigh the benefits of implementing a pure real-time system.

I have offered some examples of the differences between near real-time and real-time ingestion but often the choice between which you should pick is not as clear cut. Often there are many factors to consider like cost, ease of implementation, and what your analytics use case is.

So even if you are a super-keen engineer that can’t wait to design a brand new shiny real-time system, make sure you are liaising with product owners, data scientists, and machine learning engineers to make sure you have a strong use case!

Now let’s explore some of the best tools on the market to help you upgrade your data arsenal and take on your next streaming challenge!

Factors to Consider When Choosing Real-Time Data Ingestion Tools

The choice between real-time and near real-time ingestion isn’t always clear-cut. Many factors, such as cost, ease of implementation, and use case requirements, need consideration. Even if you’re eager to design a cutting-edge real-time system, liaise with product owners, data scientists, and other stakeholders to confirm a strong use case.

Top Real-Time Data Ingestion Tools to Upgrade Your Data Pipeline

Below are some of the best real-time data ingestion tools in 2024 on the market, each offering unique features for different use cases.

Apache Kafka: The Gold Standard for Real-Time Data Ingestion

Apache Kafka sets itself apart from the crowd as the Gold Standard for real-time data ingestion. It has become such an obvious choice for so many people as it provides a high-throughput, distributed, and fault-tolerant platform for streaming data between applications and systems, and is used by companies such as LinkedIn, Netflix, and Uber to power their data pipelines. These titans of the industry often make good technological choices, so it is a good litmus test to show how well renowned it is.

Kafka comes with a plethora of benefits that make it a versatile choice to handle any problem you could possibly throw at it. Some of the key benefits can be found below:

  • High Throughput: Kafka is capable of handling millions of events per second which is frankly absurd. This makes it more than suitable for processing large volumes of data in real time. Its high performance is primarily due to its distributed architecture and efficient message passing.
  • Scalability: Kafka's distributed architecture allows for seamless horizontal scaling. Systems rarely exist in a steady state and as your data processing needs grow, you can easily add more broker nodes to your Kafka cluster to increase throughput and storage capacity.
  • Integration & Ecosystem: Kafka integrates seamlessly with other stream processing frameworks, such as Apache Flink or Kafka Streams, enabling you to perform complex event processing, data enrichment, and transformations in real-time. 

Further to this, it comes with all the benefits of being in the Apache Ecosystem with a vibrant community of users and contributors. This means you'll have access to a wealth of resources, such as documentation, tutorials, and third-party tools, to help you get the most out of the tool

Overall, Apache Kafka is a really good all-round choice when considering choices for your real-time ingestion needs, and due to its popularity, the knowledge around it is highly distributed, meaning that there is a lot of free content available to help you get up and running in the shortest time possible.

Apache Flink is the Porsche of the real-time ingestion world. It offers low-latency and high-throughput data processing, which is highly performant and scalable. It excels at real-time due to its stateful computation and native support for event time which make it a formidable tool when dealing with the minefield that is real-time event processing.

Developed by the Apache Foundation, it has gained significant popularity in recent years for its ability to handle both real-time and batch data processing - now they are just showing off! 

Some of Flink’s best features can be found below:

  • Unified Stream and Batch Processing: The unique selling point of Flink is its ability to handle both stream and batch processing seamlessly, so if you have an integrated system, then Flink can handle that with ease. This massively reduces the headache and effort of maintaining independent systems, which makes it a hugely versatile tool.
  • Event Time Processing: Flink supports event time processing, which enables the accurate handling of out-of-order events and late data. In the real world, this is commonplace in highly dynamic systems like sensors on a car or stock market information.

In summary, Apache Flink is a hugely powerful stream-processing framework that demolishes the competition in many facets. Its unique ability to handle both real-time and batch processing, along with its flexible event-driven processing, makes it an enticing choice for building complex data processing pipelines and real-time ingestion applications.

Amazon Kinesis: Managed Streaming Service for the Cloud

Not all people will be looking to spend large amounts of time and money figuring out these complex real-time ingestion systems internally or having to hire contractors to do that for them. In this scenario, it would be much more beneficial to implement a fully managed solution, and that is exactly what Amazon Kinesis offers. 

Kinesis is a fully managed, cloud-based solution for real-time data ingestion that sits nicely in the AWS Ecosystem, which provides a scalable, real-time ingestion service.  Kinesis is, therefore, an excellent option for businesses already using AWS services, as it will fit like a jig-saw piece into already existing AWS architectures. 

Some of the key features of Kinesis can be seen below:

  • Kinesis Data Streams: This component allows you to capture, store, and process data streams from various sources, such as logs, social media feeds, and IoT devices. Kinesis Data Streams can handle terabytes of data per hour, so can take on even the heaviest streaming loads you throw at it.
  • Fully Managed Service: As an AWS-managed service, Amazon Kinesis handles all the underlying infrastructure, scaling, and maintenance, leaving you free to do the things you love like standing at the coffee machine catching up on the weekend's events!
  • Security: Amazon Kinesis provides various security features, such as data encryption, IAM roles, and VPC endpoints, to help protect your data streams and comply with industry-specific requirements.

In summary, Amazon Kinesis is an obvious choice for those already heavily integrated into the AWS cloud environment. Its real-time ingestion, processing, and analysis capabilities can handle most use cases, and the added bonus of AWS security features means that you can sleep easily at night.

Google Cloud Pub/Sub: Scalable Messaging and Event Streaming

The next tool on our list is Google Cloud Pub/Sub, which is yet another cloud-based real-time data ingestion tool that offers at least once delivery of messages and events. Pub/Sub is based on the publish-subscribe pattern, where producers (publishers) send messages to topics, and consumers (subscribers) receive those messages.

Being a Google product, its global, highly scalable infrastructure allows you to build robust, high-performance data pipelines. Much like Kinesis is to Amazon, Pub/Sub offers easy integration into the Google Cloud ecosystem. Therefore, it’s a great option for those already utilizing Google Cloud Platform.

Some of Pub/Sub’s key features can be seen below:

  • At-least-once delivery: Pub/Sub ensures at-least-once message delivery, which means that messages are guaranteed to be delivered to subscribers even if a failure occurs during message transmission.
  • Ordering Guarantees: Although Pub/Sub doesn't guarantee global message ordering by default, it provides ordering keys to ensure the order of messages within a specific key. This feature is useful for applications that require strict message ordering.
  • Integration: Google Cloud Pub/Sub integrates seamlessly with other popular GCP services, such as Dataflow and BigQuery, making it easy to build end-to-end data processing and analytics applications on the GCP platform.

In summary, Pub/Sub is a no-brainer for anyone already operating in the GCP cloud - it is fully managed and comes with all the benefits of integrations and security associated with this.
